A 65-year-old man with presumed choroideremia with preserved central vision was examined by fundus autofluorescence (FAF) and optical coherence tomography angiography (OCTA). FAF showed an isolated area of hyperautofluorescence that involved the fovea. Although the choroid capillary slab of the OCTA showed the medium and large choroidal vessels inferior to the area of retinal pigment epithelium (RPE) atrophy, the choriocapillaris was visible in a relatively wider area than the hyperautofluorescent area in the FAF images. FAF and OCTA images allowed us to detect damage of the RPE before the choriocapillaris atrophy in a case of presumed choroideremia with preserved central vision.
一名65岁疑似脉络膜视网膜炎且中心视力保留的男性接受了眼底自发荧光（FAF）和光学相干断层扫描血管造影（OCTA）检查。FAF显示一个孤立的高自发荧光区域累及黄斑中心凹。尽管OCTA的脉络膜毛细血管层显示视网膜色素上皮（RPE）萎缩区域下方的中、大脉络膜血管，但在FAF图像中，脉络膜毛细血管在比高自发荧光区域相对更宽的区域可见。FAF和OCTA图像使我们能够在一名疑似脉络膜视网膜炎且中心视力保留的病例中，在脉络膜毛细血管萎缩之前检测到RPE的损伤。
